sterling has prepared the following two-column proof below. find and fix two errors.

Sterling made his mistakes in reason 6 and reason 7.

Step-by-step explanation:

1.                (Given)

2. Draw OE as a perpendicular bisector to LN.       (Construction)

3.                (Definition of perpendicular bisector)

4.                (Definition of perpendicular bisector)

5.                (Definition of perpendicular bisector)

Since two consecutive angles and the included side of one triangle is equal to the another triangle, therefore by ASA postulate of congruent triangles,

6.                (ASA postulate)

7.                  (Definition of perpendicular bisector)

8.                (CPCTC)

Therefore the Sterling made his mistakes in reason 6 and reason 7.

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b

$12. that is my answer.
